Osprey is on the right track. The pressure at the depth of the spreading center may mitigate and "Eruption"...
The fact that this particular molten magma seems to be highly evolved (ie high silica rather than silica depleted basaltic magma... implies that an
island may be more likely to be formed.)...The situation is geochemically rare and needs careful study.
Remember, we are talking about sea floor conditions thousands of feet deep, very high pressure and low temperature conditions. This is NOT a Mount
Saint Helens situation!
So relax, have another cold one and some yellowtail sashime and life will be good! |
